The Genie 1255658GT is a genuine OEM TL Nylock Nut, M14-2.0, DIN980, 10, ZAB built for Genie SX telescopic boom lifts and ZX articulating boom lifts, including the SX-150, SX-180, SX-135 XC, SX-105 XC, SX-125 XC, and ZX-135/70. As a genuine OEM component, it is manufactured to the same dimensional and material standards as the hardware originally installed on these machines. Cross-reference part number 1255658GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- OEM-Grade Fastener Material — Manufactured to DIN980 specification at property class 10 with ZAB finish, meeting the same dimensional and torque requirements as the original hardware.
- M14-2.0 Thread Specification — The M14-2.0 thread form installs directly onto the correct mating threads without modification, ensuring a secure, properly torqued connection.
- Broad SX and ZX Boom Fitment — Compatible with multiple Genie SX super-boom telescopic lifts and ZX articulating boom lifts, covering some of the tallest machines in the Genie range.
- Nylon-Insert Locking Design — The nylon locking element resists vibration-induced loosening, maintaining clamp load even under the dynamic loads and movement cycles common in aerial lift applications.
- Genuine Genie OEM Part — Sourced directly through the Genie OEM supply chain, so the part number, thread form, finish, and property class match the original specification exactly.
A nylock nut uses an integrated nylon insert that grips the bolt thread when fully seated, creating resistance to vibration and preventing the fastener from backing off during operation. On large boom lifts that experience continuous structural movement and vibration across extended work cycles, this locking feature is critical — a fastener that loosens can compromise the structural integrity of the connection it secures. Replacing a worn or damaged nut with the correct M14-2.0 DIN980 grade-10 fastener restores the joint to its original specification and ensures the connection performs as the machine was designed.
